risoessi provide an improved construction for steamhose locks.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompany ing drawing, in whichg Figure 1 is a side elevation illustrating one form of my'improved steam-hose lock.

Fig. 2 is a plan of a portion of the same. I

Fig. 3 is a side elevation of a modified form, and Fig. 4 is a plan of the same.

In the construction and application of my improvement according to Figs. 1 and 2, known as the vertical eccentric, the numerals 10, 11 designate couplings mounted on end portions of hose members (not shown) on adjacent railway cars, said hose members forming part of the steam radiation equipment. The couplings 10, 11 carry hose heads 12, 13 respectively of common form, adapted to be mounted and secured relative to each other in such manner as to form a steam-tight joint between the hose ends. The hose heads 12, 13 are formed on their tops with transverse lugs or bearings 14, 15 respectively, adapted to be brought into adjacent and parallel relations when said heads are connected. Yoke-shaped links 16, 17 are provided for the bearing lugs 14, 15 and are formed with pivots on one end each journaled in the respective bearing lugs. The yoke-shaped links 16, 17 are secured against withdrawal from the respective bearings by meansof washers 18 and split-keys 19. Each yoke-shaped link 16, 17 is adapted to swing over and to embrace the bearing lug 15 or 14 opposite to its pivotal mounting, and has its free leg formed as a pivot on which is mounted an eccentr c clamp 20, one only of which 1s shown. It is to be understood that each hose head 12, v13 7 preferably is formed with the complete locking devices, although I have here shown [Y specification of'Letters Patent.

7 only one complete set, those connected to the head'l3 being broken" away to economize space and avoid confusion. The eccentric clamp 20 is adapted to engage the outer face of the lug 14 (or 15), each lug being formed with" a curved seat 21" for its reception, and to apply strain thereto to the end of tightly and securely joining the hose heads '12, 13. The eccentric clam 20-is secured on the'pivot of the link 16 or'17) by means of a split-key 22. The eccentric clamp 20 is formed with a bifurcated lug 23 "extending in the direction opposite to its clamping surface, and a handle 24 has one end mounted in the fork of said lug and secured to a pivot bolt 25, extending at right angles to the pivot of the link and clamp.

In use the hose heads are brought together and the handle 24 is grasped and manipulated to cause the link 16 to swing over the lug 15, after which said handle is used as a lever, and in alinement with the bifurcated lug 23, to cause the eccentric clamp 20 to engage the outer face of the lug 15 and lock in the seat 21 thereof, the parts then occupying the position indicated by the dotted lines in Fig. 1. The handle 24 may then be turned laterally on the pivot 25 to position shown in Fig. 2, where it is out of the way until again wanted for unseating the clamp 20, which is accomplished by an opposite movement of said handle. I

In the construction according to Figs. 3 and 4, known as the horizontal eccentric, the links 16, 17 are not formed with pivots on their free ends but are formed flat. A handle lever 24 is pivoted adjacent its end on a vertical axis to the free end ofthe link 16 (or 17*), by means of a bolt or rivet 26. The handle lever 24 projects somewhat beyond the pivot 26 and is formed with an eccentric clamp 27 adapted to engage the rear face of I 13, as by screws 29, and is designed to re-' ceive the handle lever 24*, when the parts are in locking position, and prevent upward" movement thereof and of the clamp 27 and link 16 (or 17*). The handle lever 24 is seated in the keeper 28 by lateral movement,

articulating on the pivot 26, in the act of seating the eccentric clamp 27. An opposite I e PatentedMa1n9, 191'5."
